Just try answering- the question
Your whole premise it that nothing in physics (that we know) allows for interstellar travel.
So...for the last time...
Do you think we know everything there is to know about physics?
It’s OK- when you have lost the argument it is good to concede a point- try it.
Learning happens only when you listen - not when you speak. When you speak you only let people know what (little) you know.
If you think the question is irrelevant than you need to go back to school and learn HOW to think, instead of WHAT to think.
If you believe that one day their will be some physics that allows time travel and we will be able to translate that into some form of useful technology, I would argue these are religious beliefs not scientific.
It never ceases to amaze me that someone like Central Va thinks that he is educated, just because he has learned to copy and paste.
Reminds me of the bar scene in Good Will Hunting.
